Module: AIOM+ (All In One Minify) for CSS, LESS, JS and HTML

[matjazp]

I think it's safe but check on dev installation first. I'm still using the old version on my few websites, with just a few fixes (although not sure which ones) - don't fix if ain't broken mantra :-). A colleague is running the new version, but he isn't using minimizing js/css functions; he uses just caching operations, no problems in last 2 months. But he just informed me that when he access the module settings in admin, it takes a long time to see the settings - I never had any problems, will report back if he finds what could be the problem.

Hi, any plans to integrate the new Dart Sass which bootstrap 5 uses by default? https://sass-lang.com/dart-sass

Hello, I'm having a strange issue, the module works fine in production mode, but when I enable the $config->debug = true; the module cannot compile my files and output this error

 

<b>Warning</b>:  A non-numeric value encountered in <b>/site/assets/cache/FileCompiler/site/modules/AllInOneMinify/AllInOneMinify.module</b> on line <b>713</b><br />/site/assets/aiom/css_b636f2192ceb48c592835de3c2d9c3b9_dev.css?no-cache=1601104220">

Any idea how to solve this? Thanks

This error also happens with PHP 8.

Modify line 707

$_timestamp = '';

to

$_timestamp = null;

Solve the error.

@David Karich Is this module still in development? Could you please update that one line that @Gideon So suggested. That solved my PHP8 (and internal server) error. Thanks!

Modify line 707 in /site/modules/AllInOneMinify/AllInOneMinify.module
$_timestamp = '';
to
$_timestamp = null;

In the document html head tag:

        if (!empty($jshead)) echo '<script src="'.\AIOM::JS($jshead).'"></script>';
        if (!empty($jsfoot)) echo '<script src="'.\AIOM::JS($jsfoot).'" defer></script>';

... both lines render the same file, containing only one of the files in the respective arrays (each array has one item, it only contains the 1st)? What am I doing wrong?

Also, including @import google fonts begets the following error:

PHP Warning: Trying to access array offset on value of type null in .../processwire/site/modules/AllInOneMinify/lib/Less/Less.php:5746

No error if I include the compiled CSS instead of LESS, but @import is used in the README examples?

[hellomoto]

Updating less.php got rid of the aforementioned LESS error though the fonts don't load anyway.

Changed the JS method allowing for a second call to generate JS to be deferred:

    public static function JS($javascripts, $js2 = false) {

        // ------------------------------------------------------------------------
        // Check if at least one file was passed.
        // ------------------------------------------------------------------------
        if(empty($javascripts)) throw new WireException('There were no files specified to minimize.');

        // Support passing of $config->scripts as argument which is of type FilenameArray
        if(($javascripts instanceof FilenameArray))
            $javascripts = (array) $javascripts->getIterator(); // Convert to array

        // ------------------------------------------------------------------------
        // Check if files exist and generating the cache file name based 
        // on the last editing of the file.
        // ------------------------------------------------------------------------
        $javascripts    = is_array($javascripts) ? $javascripts : array($javascripts);
        $javascripts    = self::_fileArray($javascripts, '.js');
        $cacheFile      = self::_getCacheName($javascripts, self::$jsCachePrefix . ($js2 ? '2' : ''), '.js');

add js to defer

For anyone trying to use this module in PHP 8, after changing the 2x lines mentioned previously in the main module file I was getting the following error at line 314 of /lib/JSMin-2.1.7.php :

ord(): Passing null to parameter #1 ($character) of type string is deprecated

The line in the file is:

if (ord($c) >= self::ORD_SPACE || $c === "\n" || $c === null) { return $c; }

Changing it to his solves the issue:

if ($c === null || ord($c) >= self::ORD_SPACE || $c === "\n") {return $c;}

@David Karich This is a super module and including the three line changes outlined in this thread would be a really nice thing if possible!

[matjazp]

@prestoav David doesn't maiantain this module anymore. In my forked version this fix is already integrated.

Hi @matjazp, thank you for the information. Could you share a link to your fork of this module? Thanks!

[matjazp]

https://github.com/matjazpotocnik/ProcessWire-AIOM-All-In-One-Minify

Note that AIOM+ has a caching component, similar to Procache. 

[prestoav]

Hi @matjazp Thanks for the information. I've be playing with your fork version this morning it's worked well.

Any chance you'll add this to the module directory?

[David Karich]

@matjazp Thank you for your work and for keeping the module alive. We can talk about adding you as an owner in the Git repo so that the module can be further developed. If you're interested, just get in touch with me.

Speaking as a user, this module is incredibly helpful and I'd love to see it back in the main module directory and continuing to me maintained. Thanks to you both.

[matjazp]

@prestoav, thanks for the compliments 🙂 I forked AIOM primarily to fix issues I was facing, and then it somehow developed into the version with the caching options. I don't use minification of CSS/JS. I think it's enough to use simple preg_replace to remove blanks. It's painful to follow and track issues for all libraries now included in the module (voku html_min, simple_html_dom, symphony css selector, lessmin, cssmin, jsmin, ...). Not worth it for those few percentages. But hey, the module works, even on PHP 8.5. Did you try/test caching options? 

@David Karich, I didn't change the class name as I wanted to preserve its name and your contribution/authorship of the module. Thanks for the module! I'll PM you.

I haven't tried the template caching quite yet but it's on my 'discovery' to-do list for sure!

[Gideon So]

Hi @

I have just installed the forked version of this module. I get the below whenever I try to clear cache in the module setting page. Any hints?

Fatal Error: Uncaught Error: Call to undefined method AllInOneMinify::getDirContents() in site/modules/AllInOneMinify/AllInOneMinify.module:1216

Fatal Error: Uncaught Error: Call to undefined method AllInOneMinify::getDirContents() in site/modules/AllInOneMinify/AllInOneMinify.module:1216

Thanks.

Gideon

[matjazp]

Please replace self::getDirContents($path); with self::_getDirContents($path); (underline is missing).

[Gideon So]

Hi @matjazp

Thanks for quick response. I guess the same.😊

Gideon

[Gideon So]

Hi @matjazp

By the way, would you update the github repository?

Gideon

[David Karich]

AIOM is alive 🙃

I am pleased to announce that the AIOM module will be further developed and supported by @matjazp. My original repository is now archived, and matjazp's fork is now the official one.

The forked version is now also listed in the Processwire module directory. This should make it possible for everyone to update the old version to the new one, either manually or via the ProcessWire upgrade module.

[DV-JF]

Great news, I've a couple of old sites where I'm still using this module. Thank you @matjazpfor taking care!

I've noticed some strange behavior on two ProcessWire & AIOM+ installations now. When I make a change in the module and click "Save," the backend page apparently gets cached. When I open the frontend in a different browser, the admin bar appears.
When I click "Empty Cache," the admin bar disappears again. But with every change in AIOM+, it reappears in the frontend.

I’ve only made the default settings and haven’t changed anything in the templates themselves ...

[matjazp]

What do you mean by "backend page apparently gets cached"? Any errors in javascript/network panel in browser? Any info in log files? I see that the layout of tabs is not correct, or at least differs from how the tabs are renered here on my browser. AIOM does not have admin bar, I have no idea what would that be. Please PM with your site details so I can check myself.

And this is what the top of the frontend looks like while you're logged out:

When I click "Empty cache," the frontend looks normal again and the admin bar disappears.
